Evans later elaborated: "What hurts the worst is he doesn't give two f-cks how I'm feeling." The MTV reality star (and mom to son Jace, 2) even accused Head, 22, of getting physical during an argument, which he later denied. "I never hit her," he tweeted.

Head, who is in the Marines, told one Twitter user that "getting girls has never been a problem for me. That's why I left Jenelle for someone better." Evans said she did eventually "call the cops" but "told them I didn't want to press charges to jeopardize his career."

On Monday, Evans uploaded a YouTube video that featured her riding shotgun in a friend's car while angrily singing RedJumpsuitApparatus' "Face Down." She dedicated the kiss-off to her ex, "Gary Motherf-cking Head."
